The present invention relates to a light emitting diode (LED) light irradiator installed in an optical module system for concentrating light for medical environmental purposes, an ultraviolet sterilizer for water purification and an ultraviolet module system for air purification, and more specifically, to a light curtain type LED light irradiator to form LED light in a curtain shape within a fluid path and recycle the emitted LED light within the fluid path, so as to enhance integration and efficiency of light. According to the present invention, in an LED light irradiator to sterilize germs included in fluid by being placed in a pipe (1) having a fluid path (2) supplying fluid through the inside and by emitting light to the inside of the pipe (1), a light irradiator is formed by the predetermined number of LEDs (101) for emitting light in a ring shape, the light irradiator formed in the ring shape is attached on the outer surface of a transparent pipe (1), and the LEDs (101) emit the light in a direction perpendicular to a central axis of the pipe (10) by power supply, so a light curtain in a film shape is generated in the fluid path (2) inside the pipe (10). Thus, germs included in the fluid supplied along the fluid path are sterilized and the fluid is purified. |
